Employing data from the 1970 Census, this study investigates whether all non-Anglo ethnics experience monetary discrimination in employment. Two minority groups at opposing positions on the socioeconomic spectrum, Japanese Americans and Mexican Americans, are compared to the Anglo population. Overrepresentation in low prestige jobs, underrepresentation in well-paid employment, and a lower minority income return relative to Anglos for similar employment are analyzed. To ensure comparability of the three population subgroups, the analysis is limited to California, to currently employed males between the ages of 25 and 64, to native born workers, and to three employment groups: private wage and salary workers, government workers, and the self-employed. Education, occupational status, and income are analyzed. The results suggest that the upward economic mobility of minority group members is limited according to minority status or ethnic group socioeconomic status relative to the Anglo population. Mexican Americans apparently earn less than Anglos because of their inferior level of schooling, while the Japanese earn less because of their concentration in lower paying employment and because they do not receive equal wages in the same detailed occupations.
